The standard library provides the ability to parse plain text
configuration files and populate a collection of values for
configuration. The module's name is changing to conform to the library
standards; see <URL:http://docs.python.org/library/configparser>.

This way, you can customise the execution of your program by modifying
configuration settings in a non-executable configuration file. It also
allows a cascade of overrides, for e.g. user-specific configuration
overrides or test-specific overrides, etc.
